The conceptualization and measurement of need: a key to guiding policy and practice in children's services.

Effective services for children must be grounded in the sound conceptualization and measurement of need. The concept of need is often misunderstood because it is used in different ways. Defining need as both a requisite and a goal is desirable. The conceptualization ought to rest on an acceptance that not only are objective and universal needs to attain physical health and autonomy requirements for all human beings, but subjective needs may also sit alongside of universal needs. The ecological/developmental perspective is best suited as a framework for assessing the needs of children. One of its tenets, the importance of understanding the interaction of risk and protective factors, is highly relevant to assessing needs. An assessment of the interaction of risk and protective factors operating in a child's life reveals the requisites and goals necessary for child development. The proposed approaches to the conceptualization and measurement of need when combined will be conducive to better assessment and intervention by social workers with children. [ABSTRACT FROM AUTHOR]
